Beyoncé: "Diva" Beyoncé's upcoming release is divided into halves: A pop-and-ballad-heavy "good girl" side and a hip-hop-and-electronica-heavy "bad girl" side. As is frequently the case in life, the good girl side is perfectly nice, but the bad girl side -- which includes this uncharacteristically edgy track -- is more interesting.

Team B: "On My Mind" From the currently unsigned side project featuring members of the Arcade Fire, Beirut and LCD Soundsystem, this endearingly slight assemblage of finger snaps and echoey vocals will make no one forget about their day jobs.

Kanye West feat. Kid Cudi: "Anyway" The latest, most promising leak from West's upcoming "808s & Heartbreak" CD is another marvel of Auto-Tune and Reagan-era beats, this time with an assist from Cleveland rapper Kid Cudi.

Megapuss: "Adam & Steve" Megapuss is the latest side project from Strokes drummer Fabrizio Moretti, teamed here with terrifying folk-hippie Devendra "Just be glad I'm wearing pants" Banhart and Greg Rogove of Priestbird. Their first single sounds like a freak pop version of the Doors, and the accompanying video is entertaining as heck, like something the Monkees might have come up with after not showering for several weeks. And taking lots of drugs.

Tone Loc feat. Peaches: "Wild Thing" (Peaches Extended RMX) On this track from Delicious Vinyl's "RMXXOLOGY," which pairs old-school hip-hop tracks with the new-school remixers who love them, "Wild Thing" gets a just-right work-over by Peaches, who adds lots of vaguely dirty cooing. Because Peaches can apparently do only that one thing.
